HYDR-OCARBOfN-BURNER.

SPECIFICATION forming part of Letters Patent No. 715,639, dated December 9, 1902.

Application filed April 5, 1900.

To all whom it. may concern Be it known that I, ALBERT F. CHACE, of Boston, in the county of Sufiolk and State of Massachusetts,haveinvented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention hasiforits object to provide a hydrocarbon-burner adapted to cause the combustion of liquid hydrocarbon in such manner as to producea flame of intense heat; and it consists in the improvements which I. will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional view of an apparatus embodying my invention, an oil-reservoir and the pipe connections hereinafter referred to being Fig, 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a section on line 3 3' of Fig. 2. Fig. 4 represents an end elevation.

The same letters of reference indicatethe same parts in all the figures.

. In the drawings, a represents an air-conduit, which receives air through a supplypipe 0, connected with a blower or other means for supplying air under pressure.

6 represents an oil-conduit located .within the air-conduit a and connected by a pipe I) with an oii-reservoir 12 which is preferably elevated above the conduit b sufficiently to create pressure by gravitation on the oilin the,

conduit 1). An air-supply pipe a, connected with the source of supply which furnishes the conduit a, enters the upper portion of the tank b so that the oil in the tank is sub- Jected to air-pressure. The oil-conduit b is provided with a contracted outlet b Figs. 2 and 3, which permits the oil to escape into thesurrounding portion of the air-conduit a, the supply of oil being regulated by a valve 01, which 'is' aifizged to the end of a rod extending through the oil-conduit and having an arm or operating-finger cl at its rear end, whereby the valve may be adjusted to vary the operative size of the outlet 6 Adjacent to the fingercl is a fixed graduated plate (1, which enables the valve 01 to be adjusted,

permitting the escape of any desired quan- Serial No. 11.723. memorial.)

tity of oil. The air-conduit a is secured at oneend to a chamberf, into which the oil is forced in an atomized condition by the airtube g, at the outer end of which the atomf between the burner-tube g and the delivering ends of the air and oil conduits, said partition aiding in the subdivision or atomization of the oil and preventing the flame from the burner from striking back to the air and oil conduits a and 5. Within the burner-tube g is a helical wireg,which causes a further subdivision of the particles or atoms of oil.

It will be seen that the air suppliedunder pressure to the conduit or and to the oil-tank b is equal in both and simultaneously causes a blast of air through the conduit at, around the oil-conduit b, and at the same time creates pressure in the tank 19?, which, together with the elevation of said tank, causes the oil to flow from the outlet b against the air- -pressure that exists in the air-conduit and in the chamber f regardless of any variations in the latter.

The blast of air attacks the drops of oil that. escape from the opening I) and atomizes the oil, carrying it through the wiregauze partition h and the burner-tube g, the result being a flame of intense heat at the outer end of said tube.

, The chamber f may be'cornsidered as; a part of the air-conduit. It is made in a separate piece detachably co nected to the air-conduit for convenience 1? construction.

It will beobserved that the chamber f is somewhat larger than the conduit a--that'is, its internal diameter is equal to the external diameter of the conduit, and therefore larger than the interior of the conduit; but since a portion of the interior of the conduit is. occupied by the oil-conduit the efiective cross-sec- .tional area of the conduit or is considerably less than the chamber f. This enlarged chamher receives theatomized oil direct from the valved outlet of the oil-conduit and permits said atomized oilto be spread out by the blast and broken up by the reticulated screen, which is in said chamber, and therefore so close to the said valved outlet as to receive the oil directly therefrom, the oil having no opportunity to condense along the in nor Wall of the conduit or chamber.

I find that the described apparatus is capable of generating either a modeigate degree of heat suitable for cooking or a much higher degree. I have with said apparatus attained a very high degree of heat capable of destroying refractory materials. The degree of heat is dependent on the adjustment of the valve.

I claim- 1. A hydrocarbon-burner comprising an air-conduit a, an enlarged chamber f detach- .ably secured to one end of said conduit, a

reticulated screen in said chamber, a burnertube projecting'froin said chamber, and an oil-conduit within the air-conduit and having a valved outlet adjacent to the point of connection between the conduit (1, and chain'- berf, the conduit a and the burner-tube bei l t .tracted outlet 11 a rod (1 ing connected to opposite sides of the enlarged chamber.

2. A hydrocarbon -burner comprising an ainconduit a, an enlarged chamberfdetachably secured to one end of said conduit, a reticulated screen in said chamber, a burnertube projecting from said chamber, the cond'uitc. and the burner-tube being: connected to opposite sidesof the enlarged chamber, an oil conduit 1) within the conduit a and having a capped outer end provided with a conextending through conduit 1) and provided with a valve (1 affixed to its outer end said valve being adapted to control the outlet 11 means for oscillating the rod, and air and oil supply connections with the conduits a. and b respectively.

In testimony whereof I have affixed my signature in presence of two Witnesses.
